190 Appendix
A maximum of one connection exists in one slave; therefore, only the target IDs
0x0000 and 0x0001 are valid in this case as well.
For a master, the target IDs 0x0000 and 0x0007 are valid.
If the maximum possible 7 devices have been configured, the query of a target ID
for which no device has been configured returns the value
MBX_STATE_ERROR_UNSPECIFIED (0x1000).
If a connection has been configured but could not be established, the query of the
corresponding target ID always returns the value
MBX_STATE_ERROR_CREATE_LINK (ox1002).
To calculate the group ID and target ID from an existing object ID and vice versa,
the following logical links must be used:
• Group_ID = Object_ID ∧ 0xF000
• Target_ID = Object_ID ∧ 0x0FFF
• Object_ID = Group_ID ∨ Target_ID
Group ID
0x0000
Wireless (status of
the wireless
connections), 0x1000
Timing 0x2000
Target Description
ID
0x0000 The query of the group status always returns MBX_STATE_OK.
An error in the overall system would mean failure of the module.
0x0000 If not all devices
in "Configuration" mode,
MBX_STATUS_ERROR_UNSPECIFIED is returned as the
group status, otherwise MBX_STATE_OK.
*)
Slave: If no device is linked for the corresponding table space,
0x0001 MBX_STATE_OK is always returned. For existing connections,
the following warnings are generated for connection quality:
Master: - MBX_STATE_WARNING_BER_HIGH
0x0001 - MBX_STATE_WARNING_BER_MEDIUM
to - MBX_STATE_WARNING_LESSTHEN_39_CHANNELS
0x0007 - MBX_STATE_WARNING_LESSTHEN_54_CHANNELS
A master can also return information about the connection status:
- MBX_STATE_OK
If the respective slave is connected or is connecting.
- MBX_STATE_ERROR_CREATE_LINK
If the slave could not connect, but further attempts to connect
are carried out (device
0x0000 For connected 750-644 I/O modules:
and - MBX_STATE_ERROR_WATCHDOG
The time since the last packet is greater than 60 x (number of
Slave: active radio channels+ 2 ms).
0x0001 - MBX_STATE_WARNING_WATCHDOG

Master: active radio channels + 2 ms).
